I used my multi gate while tracking with triggers to trigger the gates on the Heavy Brothers CD. The producer requested to be able to do this and we both worried that it may hurt the integrity of the signal path.
Happily I can report that the audio signal sounded no different with the multi gate in the chain then it did without it.
As far as how well this unit works, well, I have used Drawmers, Aphex, and Symetrix units and this Behringer worked just as well as the better ones, and better than the crappy ones.
The unit has sidechain/key inputs which makes it a very versatile gate. The audio passes through with no color and no noticable volume loss.
Two thumbs up on the Behringer Multi-Gate. A steal at $250!!!
